KAQY214 Series
cosmo
Description
The KAQY214 series is robust, ideal for telecom and
ground fault applications. It is a SPST normally open
switch (1 Form A) that replaces electromechanical relays in
many applications. It is constructed using a GaAlAs LED
for actuation control and an integrated monolithic die for
the switch output. The die, fabricated in a high-voltage
dielectrically isolated technology, is comprised of a
photodiode array, switch control circuitry and MOSFET
switches.
